Input Type Password makes Chrome Unresponsive

I'm using 4.1.1 still. I have a form with a password input type field and whenever I delete characters Chrome becomes unresponsive for a few seconds. The same behaviour does not happen in Firefox or IE.

Wasn't able to find any known issues like that. Is it possible that you have set up an event handler getting activated by the password field interaction that is taking longer on Chrome? Which version of Chrome? Which OS?

Browser hangs only if delete charts from field with inputType:'password'? And if you remove this setting, than all is right? What happens if you leave only this field in the panel? And if you set width&height for the panel?

Thanks for the response. A normal text field doesn't encounter the same problem. Removing it to be the only item in the panel improved the performance but it still hangs for approximately half a second when the field is cleared. Removing emptyText property didn't help this either.
